Jump across the solar system with "Planet Jump"! Leap on 8 planets & 20 moons, with fun facts and an astronaut buddy. Earth: 40 cm, Moon: 2m, Deimos: 1.5 km!
Get to know all the 8 planets and 20 moons of our amazing solar system. Each has its own gravity depending on its size. Deimos is a tiny moon of Mars. Jumping there would take you over a kilometer in the sky!
We have landed only on the Moon, Mars, Venus and Titan so far. All the other worlds are waiting for your exploration.
Astronaut Nick will accompany you on all your space missions.
Use the integrated calculator which can help you with scaling planet sizes and their distances.
Directly from the homescreen you can go to a randomly selected celestrial body and jump right away after you called the astronaut. Interrupt any long jump by pressing the "Stop jump" button. Select another planet with the left and right arrow keys. You will always proceed in the correct order from inner planets and moons to the outer planets and their moons.
Your tiny astronaut buddy will be with you every jump of the way, cheering you on as you defy gravity and common sense. So, what are you waiting for? The cosmos is your playground!
Earth is tiny compared with the biggest planet Jupiter. Jupiter has 11 times the size of Earth. But our Sun is 10 times as big as Jupiter.
Our biggest planet Jupiter has already 95 moons. The biggest moons are also called the Galilean moons because they were discovered by Galileo Galilei in 1610. They are called: IO, Europa, Ganymede and Callisto.
The Jupiter moon Ganymede and the Saturn moon Titan are bigger then the planet Mercury and larger then our own moon.
...how do you know what the surface of Ganymede looks like? How do you calculate the hangtime for a jump?
Actually I don´t. Currently there are only surface fotos from the Moon, Mars, Venus, Titan and some Asteroids. All the others are left to our imagination.
I calculated each jump with the average height of 43 centimeters on earth with the local gravity of the celestrial body.
NASA started using the metric system already in 1970. The Appollo guidance system used metric units internally but displayed values in inches and feet to the astronauts.
Discover our solar system by jumping on all 8 planets and 20 moons.
